Understanding Forex Spreads and Their Impact on Trading

When you dive into the world of Forex trading, you’ll quickly encounter the term “spread.” It’s a fundamental concept that directly affects your trading costs and profitability. Simply put, the spread is the difference between the price at which you can buy a currency (the ask price) and the price at which you can sell it (the bid price). Think of it like the difference between what a shop pays for a product and what they charge you – that margin is how they make money. In Forex, brokers make money in a similar way through the spread.

Understanding Bid and Ask Prices

Before we delve deeper into spreads, let’s clarify bid and ask prices. The bid price is the highest price a buyer (like your broker or another trader) is willing to pay for a specific currency pair at a given moment. Conversely, the ask price (also called the offer price) is the lowest price a seller is willing to accept for that currency pair. The bid is always lower than the ask, and this difference is what creates the spread.

Imagine you’re looking at the EUR/USD currency pair. You might see a quote like this: Bid Price: 1.1000, Ask Price: 1.1002. The spread in this instance would be 0.0002, or 2 pips (more on pips below). When you want to buy EUR/USD, you buy at the ask price, and when you sell, you sell at the bid price. It’s important to understand this dynamic because you will always buy slightly higher than the current market value and sell lower.

What Exactly is a Pip?

You heard the term “pip” above, and it’s essential to know it. Pip stands for “percentage in point,” and it’s a very small measure of change in a currency pair. For most currency pairs, one pip equals 0.0001 (like the example with EUR/USD). However, for currency pairs that involve the Japanese Yen (like USD/JPY), one pip equals 0.01. So, understanding pip values for the specific pairs you trade is very important.

The spread is most often quoted in pips. As we saw before, a spread of 1.1000 bid and 1.1002 ask means a spread of 2 pips. When you buy, the price needs to move at least 2 pips in your favour before you even begin making a profit because of the spread.

Types of Spreads

Forex brokers offer different types of spreads, generally falling into two main categories:

  • Fixed Spreads: As the name suggests, fixed spreads remain constant regardless of market volatility or trading volume. Brokers offering fixed spreads tend to act as market makers. This means they don’t send your orders directly to the market, but rather are counter-parties to your trades. This type of spread is often easier to predict and can be preferable for beginners who prefer to know their trading costs up front and budget accordingly.
  • Variable Spreads: Variable spreads (also called floating spreads) fluctuate based on market conditions. During periods of high trading volume or significant economic events, spreads can widen, sometimes even significantly. Conversely, at times of low liquidity, or quiet markets, spreads might become narrower. These spreads are usually found at brokers who act as intermediaries, passing your orders directly to the interbank market or liquidity providers. Often advertised as “lower spreads”, they can be unpredictable, but can be cheaper than fixed spreads during calmer markets.

How Do Spreads Impact Your Forex Trades?

Spreads directly impact your trading costs, because you are effectively buying a currency for more (the ask price) than you would get back if you instantly sold it at the opposite price (the bid price). This means every time you open a trade, the initial trade is already in a losing position. This makes spread a major consideration when planning your trading strategy.

  • Transaction Cost: Spreads are a transaction cost built into every trade. The wider the spread, the more it costs you to enter a trade, making your break-even point further away from your trade entry price. Conversely, narrower spreads reduce your costs and increase your ability to achieve a profit.
  • Scalping Challenges: Scalping involves making very small but rapid trades. Because of the narrow profit targets, wide spreads present a serious challenge to scalpers. The wider the spread, the harder it can be for scalpers to turn a profit.
  • Impact on Larger Trades: Even the smallest spread becomes relevant when you start trading larger positions. Because profits and losses are scaled to position size, even a spread of a few pips can have a significant impact on overall profitability.
  • Psychological Effect: When a trader sees that their position is already showing a loss (due to the spread), this can induce a feeling of frustration or even panic. This underscores the importance of understanding the impact of spreads and not being surprised by the negative starting position. A careful trader takes this into account, and makes sure that their strategies take this into account and have an appropriate expectation for the immediate loss.

Factors That Influence Spread Size

Several factors can influence the spread size you encounter while trading:

  • Market Liquidity: Highly liquid currency pairs (such as EUR/USD) with lots of buyers and sellers typically have tighter spreads. Less traded currency pairs or exotic pairs usually have wider spreads.
  • Market Volatility: Periods of high trading volume or significant news releases tend to cause spreads to widen due to the increased risk and uncertainty.
  • Broker Type: As mentioned earlier, different brokers offer different types spreads, based on whether they act as a market maker or intermediary. Brokers also vary greatly on how much markup, and how these spreads vary with market conditions. Broker reputation and competitiveness also has a strong impact on spreads.
  • Time of Day: The time you trade also affects spreads. When major trading sessions overlap (for example, the London and New York sessions), spreads on major currencies tend to be narrower due to higher liquidity. Outside of these times, liquidity may shrink and wider spreads can be common.

Strategies to Manage Spreads

While you can’t eliminate spreads, here are several strategies to help manage and mitigate their impact:

  • Choose the Right Broker: Research and choose a broker that is well-regarded, offers spreads that are in the range you want, and are competitive with others. Some brokers specialise in fixed or variabe spreads, and this could inform your choice of strategies.
  • Trade During Peak Hours: Stick to trading times when spreads are usually the tightest. This usually mean trading during times when markets have high trading volume.
  • Trade High Liquidity Pairs: Focus on major currency pairs, which generally have tighter spreads than less liquid or exotic pairs.
  • Consider the Cost in Your Trading Strategy: Factor the typical spread of a currency pair into your trading strategy. If you prefer to scalp, consider the average spread of the instruments you tend to trade, and how many trades you need to execute in order to break even. Make sure your strategies’ goals have enough room to take spread into account.

Conclusion

Understanding spreads is critical for any successful Forex trader because it directly impacts your transaction costs and, therefore, your profitability. By knowing what bid and ask prices mean, how spreads relate to your trading, and when they are likely to change, you can avoid some of the surprises that can often occur. Carefully choosing your broker, considering different factors that influence spread size and trading strategies while taking the spread into account, can help mitigate the impact of the spread on your trading outcomes. This knowledge is crucial to develop a well-rounded and successful trading strategy.

Frequently Asked Questions

What is the difference between a fixed and variable spread?

Fixed spreads remain constant, whereas variable spreads fluctuate based on market conditions and liquidity.
How do spreads affect my trading profitability?

Spreads are effectively a transaction cost, and the wider the spread, the more it costs you to open a trade, meaning your trades need to move into profit to compensate for the initial loss due to the spread.
Why do spreads sometimes widen?

Spreads tend to widen during periods of higher volatility, lower liquidity, or during significant news announcements, making the price of the asset more uncertain and the risk for brokers to participate greater.
What is the difference between a Market Maker broker and an ECN broker?

A market maker broker is a counter-party to your trade. This type of broker offers fixed spreads and usually does not send your trade to the exchange. An ECN broker passes your order to the market and offers variable spreads.
What is a pip?

A pip (percentage in point) is a very small unit of change for currency pairs. For most pairs, it is equal to 0.0001, expecpt for pairs with JPY where it is 0.01. Spreads are usually expressed in pips.
Does the spread guarantee profit for the broker?

No. The spread is the broker’s means of making money from acting as an intermedidary to your trades. However, this does not guarantee a profit for the broker, as they also run operational costs. Brokers also make money on different levels of leverage. However, the spread is often the main method through which a broker covers their expenses.
